GENERAL

WARNING: Hazard of Shock. Disconnect all power before installing, servicing or replacing heaters.

Chromalox Cast-Iron Immersion Heaters are generally used for metal-melting applications such as solder, lead, tin, stereotype metal, babbitt (with 4% or less copper) and other soft metals where maximum working temperature is 950 ˚F.

Note: Not suitable for immersion in zinc or aluminum.

1.Heater Construction Characteristics —

A.High quality resistance wire held in place by compacted mag- nesium oxide in heavy wall steel sheath cast in iron.

B.Large heat output at relatively low watt densities.

C.Excellent heat transfer.

D.A rugged, cast iron terminal box protects the terminals against spillage and abuse.

WARNING: Users should install adequate back-up controls and safety devices with their electric heating equipment. Where the consequences of failure may be severe, back-up controls are essen- tial, including GFCI (Ground Fault Circuit Interrupters). Although the safety of the installa- tion is the responsibility of the user, Chromalox will assist in identifying equipment options.

INSTALLATION

1.Before installing the type CIT heater, inspect it for possible dam- age which may have occurred during shipment. Also, check to insure that the line voltage is the same as that stamped on the nameplate.

2.CAUTION: Mount heater in the tank so that the liquid level will always be above the effective heated portion of the heater. If the heater is not properly submerged, it will overheat and damage the heating elements and create a possible fire hazard due to exces-

sive sheath temperatures.

WARNING: When melting solids by direct immersion, a surface vent should be provided to allow gases to escape.

A.Over-the-Side

Models CIT-1612 and CIT-1619 (see Figure 1 - for use in flat bottomed and straight-sided vessels); CIT-2219 and CIT-23 19 (See Figure 2 - for use in sloping vessels) are designed for over- the-side installation.

1.To resist buoyancy of heater in heavy metals, securely mount heater to metal crucible by clamping.

CAUTION: Do not support or suspend heater by the tubular section adjacent to the terminal box as the tubular section will be damaged by bending.
